“…However, there are many interfering factors which encumber the application of such methods in biological samples (e.g., body fluids). [60]. Most of the current applications of perchlorate determination in various environmental and clinical samples are based on ion chromatography.…”

Interest in perchlorate as environmental pollutant has increased since 1997, when high concentrations have been found in the waters of the Colorado River, USA. Perchlorate is very persistent in nature and it is slowly degraded. Although harmful effects of large doses of perchlorate on thyroid function have been proven, the environmental effects are still unclear. The primary objective of the present review is to collect prevailing data of perchlorate exposure and to discuss its impact on human health. The results show that more than 50% of reviewed works found significant associations of perchlorate exposure and human health. This review consists of the following sections: general information of perchlorate sources, its properties and determination methods, role and sources in human body including food and water intake, overview of the scientific literature on the research on the effect of perchlorate on human health from 2010 to 2020. Finally, conclusions and recommendations on future perchlorate studies concerning human exposure are presented.

“…In contrast, a very simple approach based on the extraction-spectrophotometric determination of ClO 4 − can use various dyes, e.g. , neutral red, 92 brilliant green, 84 and Olympic green, 84 to form complexes with perchlorates, which can be extracted by different solvents. However, various endogenous species show interference using this approach.…”

“…Gravimetrical quantitation was feasible using tetraphenylarsonium chloride, 76 tetraphenylphosphonium, 83 and antipyrine and its derivatives. 84 In general, this method could only detect milligrams and tens of milligrams of ClO 4 − in 1 L of water. In this context, it is possible to use potentiometric precipitation titration for ClO 4 − using quaternary ammonium compounds as titrants.…”

“…Various analytical techniques have been used for perchlorate determination [4,5,6,7,8,9,10,11,12,13,14]. Among of these methods are titrimetry [6], gravimetry [7], dye extraction spectrophotometry [8,9], atomic absorption spectrometry (AAS) [10,11], ion chromatography (IC) [12,13], and mass spectrometry based on electrospray ionization [14].…”

Herein, we present reliable, robust, stable, and cost-effective solid-contact ion-selective electrodes (ISEs) for perchlorate determination. Single-walled carbon nanotubes (SWCNTs) were used as solid-contact material and indium (III) 5, 10, 15, 20-(tetraphenyl) porphyrin chloride (InIII-porph) as an ion carrier. The sensor exhibited an improved sensitivity towards ClO4− ions with anionic slope of −56.0 ± 1.1 (R2 = 0.9998) mV/decade over a linear range 1.07 × 10−6 – 1.0 × 10−2 M and detection limit of 1.8 × 10−7 M. The short-term potential stability and the double-layer capacitance were measured by chronopotentiometric and electrochemical impedance spectroscopy (EIS) measurements, respectively. The sensor is used for ClO4− determination in fireworks and propellant powders. The results fairly agree with data obtained by ion chromatography.
